Princess Ceingar was
one of the many daughters of King
Brychan of Brycheiniog (Brecknockshire) in Wales, and she grew up
with the rest of his vast family at the Royal & Christian Court at Garthmadrun
(Talgarth). She eventually married the warrior king, Gwynllyw
Farfog(the Bearded), from adjoining Gwynllwg. The two
would have known each other well, for Gwynllyw was the widower of
Ceingar's elder sister, Gwladys. Her
step-children were already adults, but Ceingar soon had her own family,
becoming the mother of St. Cynidr of Glasbury. Nothing else seems to be
known about her. She is supposed to have founded a church called Llech
Maelienydd in Maelienydd, although this is unidentified and could be a
mistake. Her real church may be at Kentchurch in Herefordshire. It was
first dedicated to a St. Cein and this lady is usually assumed to have
been Ceingar's sister of that name.
However, considering the proximity of her son's foundation at Kenderchurch,
a dedication to Ceingar seems more likely.
